Hi, good day!
You can upgrade from Windows 11 Home to Pro by going to Settings > System > Activation.
Under Upgrade your edition of Windows, select Open Store to purchase the Windows 11 Pro upgrade, or choose Change product key if you already have a valid Windows 11 Pro product key.
After completing the upgrade, restart your PC if prompted.
Are you planning to purchase the Pro upgrade through the Microsoft Store, or do you already have a Windows 11 Pro product key?
I look forward to your update and am willing to collaborate with you until we resolve the issue. Keep me posted by clicking "Add comment" below.
